Finding a measure of climate that can be successfully used to stir up public anxiety and fear is getting tougher for climate alarmists, as rowing back on earlier claims and scenarios – or at least postponing the supposed days of reckoning – becomes the order of the day.
Tony Abbott may have annoyed the climate change mob with his speech in London, but a far more serious problem for that industry is an admission that global temperatures have not been following climate models, says Climate Change Dispatch.
Besides the two papers making that admission, including one in Nature Geoscience, that massive industry also faces the problem of a possible La Niña this year, which will pull global temperatures down.
Selling disaster stories about rising temperatures, the main way the industry justifies itself, is harder if temperatures are falling rather than rising.
The June 19 paper, Causes of differences in model and satellite tropospheric warming rates, states in part: ‘We conclude that model overestimation of tropospheric warming in the early 21st century is partly due to systematic deficiencies in the post-2000 external forcings used in model simulations.’
Scientists have made this observation before and been bitterly attacked for their troubles, but this paper is notable for including, as authors, the global warming leading light Professor Michael Mann, of Pennsylvania State University and one of Australia’s most distinguished scientists in this area, Professor Matthew England of the University of NSW.
In other words, the climate establishment has finally conceded some ground by agreeing that climate models may not be right all the time.
